  • Patent number: 11911988
    Abstract: A manually operated press comprising an actuating member coupled to a shaft, wherein an actuation of the actuating member is converted into a stroke movement of a press ram coupled to the shaft, and hence also into a change in a relative position of the press ram. The press furthermore comprises a reset mechanism for resetting the actuating member, which reset mechanism counteracts the actuation of the actuating member and causes a return movement of the press ram opposite the stroke movement. The reset mechanism comprises a spiral spring.

  • Patent number: 11850816
    Abstract: An arbor press includes a limiter for limiting load and/or travel of a ram used to press on an object. The ram includes a pair of pieces, a shaft and a sleeve, which are capable of relative translation, modulated by the spring. The spring may be preloaded, and configured to prevent overloading of the object, by limiting the transmission of force through the ram. The ram may also be configured to limit travel of the ram. The arbor press may include gearing to translate rotational movement of a handle to translational movement of the ram. The gearing may include a rack that is part of or is coupled to the shaft, and a pinion that is connected to the handle. Parts of the arbor press may be enclosed in a housing, to contain debris from metal-to-metal sliding in the arbor press, facilitating use in clean rooms.

The drive unit includes a rotatable main shaft carrying up to six cam discs each of which may be associated with a press. This arrangement permits the processing of more than one process area on a leadframe strip in the same press cycle in one tool at a time enabling the tools to be placed closer together to shorten the processing line. The tool drive apparatus may also include a latch assembly which, when activated, creates a larger tool-receiving space for repair and maintenance of the tool in one press without affecting other presses in the processing line.

  • Patent number: 6203312
    Abstract: A clamping apparatus for a tiebarless injection moulding machine is arranged to absorb all of the clamping forces. The machine has a machine frame supporting a fixed platen and a movable platen which carry mould halves. The movable platen is slidable along linear guide rails as is a force transmission member or second movable platen incorporated in a drive for the movable platen. The drive comprises a hydraulic cylinder and piston unit. A clamping structure has two, parallel clamping frames, each of which is substantially U-shaped so that upstanding clamping arms are defined in each clamping frame. Each clamping arm terminates in a respective force transmission part which has a curved surface and which abuts a respective one of the fixed platen and the second movable platen. When a moulding operation is undertaken, the mould halves carried by the fixed and movable platens are brought into clamping contact.

    Abstract: An injection molding machine with a substantially C-shaped machine frame has one leg on which a stationary die platen is mounted and another leg on which a closing mechanism for driving a movable die platen is mounted. An articulated part which comprises a girder extending in the longitudinal direction of the machine is arranged between at least one die platen and the machine frame and is- deformed when a closing force is applied which tips the die platen in relation to the associated leg of the machine frame. The horizontal central axis (8) of the die platen, which is determined by a centering mechanism of the die, extends completely inside the girder (6) and the cross-section of the articulated part (7) increases in size in the same direction, starting from the central girder (6).

    Abstract: A bump leveling method and a bump leveling apparatus in which the leveled height of bumps can be made constant and meet the change in thickness of an IC chip. A pressing force under which one bump is deformed to a prescribed height is measured. Thus, the pressing force under which a plurality of bumps can be deformed and leveled can be set. A load cell detects that a prescribed pressing force is exerted on the bumps and this pressing force is maintained, so that the plurality of bumps can be leveled up to the same prescribed height.
